Lost, mislabeled, and mishandled surgical and clinical pathology specimens: A systematic review of published literature.

Objectives: To perform a systematic review of published academic literature related to lost, mislabeled, and mishandled surgical and clinical pathology specimens during the preanalytical stage.
Methods: The authors used Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines to search PubMed, MEDLINE, Web of Science, and Scopus for relevant articles published from January 1, 1990, to May 1, 2023.
Results: The authors screened 1313 articles and identified 44 peer-reviewed, English-language articles published between 1990 and 2021 for inclusion in the final systematic review. Most articles (n = 36) reported results from US-based facilities. Articles primarily focused on general clinical and general surgical pathology. Analysis of the articles revealed that articles reported a range of methodological approaches, including incident reports, implementation analyses, case studies, and commentary recommendations. Most articles focused on mislabeling errors (61.3%) and missing or lost specimens (18.2%), while several articles combined specimen errors (20.5%). Several implementation studies (22.7%) reported using multiple interventions to mitigate errors. Implementation efforts reported between 70% and 100% reduction in pathology errors.
Conclusions: The review highlights the limited research on the topic, with an average of 2 articles per year discussing lost, mislabeled, or mishandled specimens. Intervention studies addressed The Joint Commission's patient safety goals for laboratory practice. More research is needed about error incidents and reporting in non-Western countries to gain a more global perspective on the topic.
